We're migrating from StarTeam (aka "the horrible") to SubVersion (aka "the alleged great"). We've already migrated the files by doing a "dumb" commit to all files and started working on the SubVersion repository.

However, we're still forced to use StarTeam because we lack the per-file history of check-ins. Is it possible to inject that history into SubVersion after the first check-in has been done? If yes - how?
